The Toxic series is as high-end as Sapphire's custom design can go and make a return to the high-end segment after five years. > The Sapphire Toxic lineup is well known for offering one of the best custom designs on AMD's Radeon graphics cards. The last Toxic series graphics card we got to see was the Radeon 390X TOXIC which launched all the way back in 2016. It's been five years since Sapphire released brand new Toxic or Atomic variants. The main reason was mostly due to poor demand for AMD GPUs in the AIB market but ever since Navi, things have changed and AMD's AIBs are offering top-tier designs with each launch.
